The Seek Select 4/3 Back Zip combines high-tech materials for ultimate warmth and stretch. ION's premium wetsuit line features Graphene Lining - an incredible heat conductor that makes sure you stay warm on the water. Only high-quality materials were used to make the Seek Select the most progressive wetsuit without compromises. A minimalistic panel design allows for limitless freedom of movement while sealed seams prolong the lifetime. Made to explore the toughest conditions, ION added Graphene_Plush throughout the torso and legs. Hot_Stuff 2.0 lining provides additional warmth at the arms and shoulders. To increase flexibility and comfort in this crucial area, ION uses a new rhombus-shaped outside lining that stretches easily, thanks to its unique structure. Seek Select Backzip models feature additional protection pads at the shins.
